Question about Ford Laser
We have removed the Thermostat, but it still overheat. When we've check, the radiator fan should be running when the engine goes hot, but it doesnt and the temperature goes up. but when we've tried removing the Sensor, the fan runs, but the temperature goes to zero. Is it because we have a faulty sensor?
Could be the sensor , this pc is not expencive you try to buy it changed and so you will eliminate one possible couse. have some one scans your car for trouble codes thats your shortcut to find the problem.

It is not the fault: for long time Renault has that concept, that is to prevent engine oveheating when coolant circulation is suddenly stopped.
Radiator fan can continue to work up to 10 minutes after engine is off. You should worry about it only if it wouldn't stop even after 10 minutes.

I had the same overheating problem in my jeep ! My problem was finaly found out to be the clutch in my fan its a different kind of clutch system it work as this. When your jeep gets warmer the tighter your fan clutch gets .While cool your fan moves slowly. now to test your clutch just warm up your jeep and rev it up a bit if your fan dose not pick up speed then it is sliping.What will come out of this is that you fan will the seez and run full all the time. if you jeep dose not overheat wile moving then it is not your thermo stat period.

Cooling Fan Temp Sensor is the First thing You Check (with what you have described) Cooling Fan Should ALways come On When The A/C is turned On as A/C Adds A Load to Engine, If Temp Sensor is Faulty it Will Not Give GROUND Signal to ECM >For COOLING FAN >RELAY to Give ground and turn ON The Fan.
There ARE 2 temp Sensors that Serve Different Purposes 1 is for Dash READING GAGE & Or TEMP LIGHT the Other is For ECM or Fan Relay (SAME Thing) you Said>""can disconnect the sensor and fan continues to run" < This Leads me to think you Changed the Wrong One. Not Questioning your Skills Just Here to Help.
TEMP SENSOR FOR 3.1L V6 is Located upper RH rear of engine compartment, near exhaust system. Temp SENSOR for 2.3L Engine is Located in LH rear of engine compartment.
I Hope this Helps Lead you to a NON-OVERHEATING Pontiac.
Good Luck and Have A Great Evening. rejakwilson

You will find this sensor where the fat hos comes from the radiator and conects to the engine block. It would be on the housing where the thermostat is located. If it is not there you should look for a sensor that has a wire connected to it anywhere on the engine block where a water inlet is located. I hope this helps. Don't forget to rate my answer, thanks.
